Prediction of thermal shock behavior of alumina based refractories: Temperature difference, fracture resistance parameters and water quench
(Trans Tech Publications Ltd, Durnten-Zurich, 2001)
In this paper temperature difference and fracture resistance parameters were used for prediction of thermal shock behavior of the samples. Materials were alumina based commercial refractories with different content of Al2O3 ...
Material properties and thermal shock behavior of alumina based refractories
(Belgian Ceramic Soc, Mons, 2001)
Materials were five alumina based commercial refractories with different contents of ( Al2O3 + TiO2) from 28 % to 78 %. Thermal and mechanical properties of the chosen materials, were measured using standard laboratory ...
Structural characteristics of bright copper surfaces
(Journal of Electroanalytical Chemistry, 2001)
In this work, the structures of copper surfaces polished mechanically and polished both mechanically and electrochemically, as well as copper coatings obtained in the presence of basic and top brightening addition agents ...
Fractal approach to ac impedance spectroscopy studies of ceramic materials
(Kluwer Academic Publ, Dordrecht, 2001)
A novel fractal model for grain boundary regions of ceramic materials was developed. The model considers laterally inhomogeneous distribution of charge carriers in the vicinity of grain boundaries as the main cause of the ...
Computational studies in the AlPO4-34 system
(Kluwer Academic Publ, Dordrecht, 2001)
The lattice energies of the as-synthesized fluoride-containing chabazite-like aluminophosphate (AlPO4-34F) and of the corresponding metal-substituted materials [MeAPO-34F, Me = Mn(II), Co(II), Ni(II)] have been calculated ...
Synthesis and characterization of thermoplastic poly(ester-siloxane)s
(Wiley-Blackwell, 2001)
Two series of thermoplastic poly (ester-siloxane)s, based on poly(dimethylsiloxane) (PDMS) as the soft segment and poly(butylene terephthalate) as the hard segment, were synthesized by two-step catalyzed transesterification ...
A study of HAp/PLLA composite as a substitute for bone powder, using FT-IR spectroscopy
(Elsevier Science Ltd, 2001)
Chemically synthesized hydroxyapatite/poly-L-lactide (HAp/PLLA) composite biomaterial was studied in vivo. The biocomposite was implanted into Balb/c Singen mice and after 1 and 3 weeks removed from their organisms and ...
Pressure drop in a countercurrent gas-flowing solids-packed bed contactor
(American Chemical Society, 2001)
The equations for prediction of pressure drop in countercurrent gas-flowing solids-packed bed contactors are proposed. The correlations are based on all available data for various constructions, packing elements, and gas ...
HPLC behavior and hydrophobic parameters of some anilides
(Springer Heidelberg, Heidelberg, 2001)
The chromatographic behavior of para substituted anilides of 2,2-dimethylpropanoic, benzoic and alpha -phenyl acetic acid has been studied by reversed-phase high performance liquid chromatography HPLC was performed on a ...
Immobilization of invertase on a new type of macroporous glycidyl methacrylate
(Kluwer Academic Publ, Dordrecht, 2001)
Invertase was immobilized via its carbohydrate moiety. The immobilized enzyme has a specific activity of 5500 IU g(-1), with 45% activity yield on immobilization. In a packed bed reactor, 90% 2.5 M sucrose was converted ...
